[英]mysql2 gem failing to install on Windows 7: failed to build gem native extension
我們嘗試了這篇SO帖子中有關使用mysql2 gem糾正安裝錯誤的建議,但問題仍然存在。 我們還查看了其他類似這樣的 SO帖子,但是沒有一個幫助。
我們在Windows 7上處於3.2.12的軌道上。
libmysql.dll
安裝在C:\\RailsInstaller\\Ruby1.9.3\\bin
,盡管已於2013年3月安裝。
錯誤:
Using mongo_mapper (0.12.0)

Results logged to C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql2-0.3.15/ext/mysql2/gem_m
An error occurred while installing mysql2 (0.3.15), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.15'` succeeds before bundling.
編寫了有關如何執行此操作的更新 (在我們不得不做很多之后):
C:/mysql-connector
) gem install mysql2 —platform=ruby — '—with-mysql-dir=”C:\\mysql-connector-path”'
原因
失敗的原因是因為Win 7沒有安裝MYSQL庫,這意味着Ruby無法引用安裝gem所需的文件。
您需要安裝正確的文件(以后可以將其刪除)。 看來您安裝的是錯誤的,這可能是gem無法安裝的原因
希望這可以幫助!
